Python实现幸运7骰子游戏时无法退出内层While循环问题求助

问题修复说明 #

• 布尔条件逻辑错误
  你写的playing == 'Yes' or 'yes'语法逻辑不成立，or右侧的'yes'作为非空字符串，布尔值永远为True，所以无论playing变量的值是什么，这个判断条件永远成立。
  建议修改为更简洁的playing.lower() == 'yes'，可以同时兼容大小写输入的Yes/YES/yes等情况。

• 变量赋值误用比较运算符
  代码中两处接收用户是否继续游玩的输入时，都写成了playing == input()，==是相等比较运算符，不会修改左侧变量的值，所以playing变量从第一次赋值后就从未更新，导致退出逻辑不生效，需要把==修改为赋值用的单等号=。

修正后完整代码 #

import random

# 初始化变量
times_played = 0 

# 询问是否开始游戏
print('Would you like to play Lucky 7s? Type Yes or No.')
playing = input()

if playing.lower() == 'yes':
    print('How much would you like to bet?')
    user_total = int(input('$ '))

while playing.lower() == 'yes':
    die1 = random.randint(1,6)
    die2 = random.randint(1,6)
    dice_total = die1 + die2

    if dice_total == 7:
        print('You won $4!')
        times_played += 1
        user_total += 4
        print('You have $', user_total, '.')
        print('Would you like to keep playing?')
        playing = input()
        if playing.lower() == 'no':
            break
    else:
        print('Sorry, you lost.')
        times_played += 1
        user_total -= 1
        print('You have $', user_total, '.')
        print('Would you like to keep playing?')
        playing = input()
        if playing.lower() == 'no':
            break

print('Thanks for playing.')
print('You rolled', times_played, 'time(s).')
